TYPEWRITING MACHINE.

Application led June 11,

Be it known that I GEORGE A. SEIB, citizen of the United States, and resident of Ilion, in the county of Herkimer and State useful Improvements in Typewriting Machines, of which the following is a speci- 'cation i My invention relates to typewriting machines and more particul-arly to accent Writing means.

The main object of the invention, generally stated, is to provide simple and etlicient means of the character referred to and yet obtain plenty of room in the type basket for the accent type-bars or blocks.

It has been found lto be desirable to provide means whereby a letter to be accented may first be written and then after a letterspace movement of the platen to add an accent mark above or below said letter with the aid-0f a dead key, or one which may be actuated to print an accent mark without effecting a feed of the carriage. It has also been found desirable to provide for writing an accent character with bothupper and lower case types so that fewer accent keys may be required in a keyboard. However,l

certain practical difficulties have been encountered to the attainment of these ends (especially in a machine 0f the general character in which my invention is shown embodied) but these I have overcome, as will hereinafter more clearly appear.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following specification and particularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference characters indicate corresponding parts in the various views,

Figure 1 is a fragmentary fore-and-aft centra-l vertical sectional view. with parts omitted, of an improved No. 10 Remington machine embodying my invention.

Figure 2 is a detail fragmentary front view of the segment and some of its associated parts` the view showing the lefthand accent type bar at the printing point.

Figure 3 is a like view showing the right-l hand'accent type bar at the printingpoint. A Figure 4 isl a detail fragmentary plan view partly in section and showing the two 1921. serial m. 476,768.

extreme left-hand type bars of the series as they appear when at rest in the basket.

Figure 5 is alike view of the two extreme right-hand type bars.

Figure 6 is a fragmentary front view of a segment slotted to receive two accent type bars at the right-hand end of the series.

Figures 7 and 8 are views 0f the lefthand and right-hand accent keys respectively. Figure 9 is a representation of the different accent marks written as they appear over accented letters and in each instance after the letter is written.

The frame of the machine comprises a base 1, ,corner posts 2 and a topplate 3, over which latter a carriage (that carries a platen 4) is adaptedv to travel from side tol and, through the arms 8 and 9, rock a shaft 10 and ,transmit a rearward movement from a centrally disposed arm 11 on -said shaft to a link 12 which operates the carriage escapement, as disclosed in the patent to Oscar Woodward, No. 1,342,489, datedJune 8, 1920.

The various segmentally arranged type bars are mounted in guide or bearlng slots in a type bar segment 13 and on a pivot wire 14 which is arranged in an arc;` the type bars moving upwardly and rearwardly to strike against the front face of the platen 4. In moving to the printing position each type bar enters between the jaws of the usual center 'guide 15. In the present instance I have shown a type bar segment having fortyfour guide slots. In the specific construction shown the first forty-three of these slots, counting from left to rightLand all of which except the first are indicated by the reference numeral 16, are radially disposed; all radiating from a common point, as indicated by the dotted lines ai and e in Fig. 3. The body portions of all of the bars mounted in these radial slots move in radial planes corresponding to said slots. The right-hand terminal slot 18, however, is cut in a non-radial plane, indicated by the sov dotted line b in Fig. 3. lt will be seen that the upper end of the line 'b is, in the present instance, about l of an inch below the point of convergence of the lines a and a, the line a, representing the plane of the left-hand terminal radial slot 17, for purposes which will hereinafter appear. ln the present instance I utilize the terminal radial slot 17 at the left-hand end ofthe series and the non-radial slot 18 at the right hand of the series in which to mount respectively the two type bars 19 and 20 which are to write the accent marks. It should be understood however that a greater or less number of such accent bars may be provided, as will presently appear. Each accent type bar in the present instance carries a type block 21 with two accent types 22 thereon, one in the upper case position and the other in the lower case position, so that. each type bar may print an accent mark in each case position. Each of the accent bars is bent laterally at its point ofconvergence, as indicated at 23, like the corresponding bends in the ordinary side type bars 7 so as to properly enter the type guide 15. However, the type bar 20 in addition has two eXtra bends, or a double bend as indicated at 24 and 25, so as to off-set its type block to write with eith'er type a letter space to one side of the normal printing point, as indicated by the dotted line c in Fig. 3. In the present instance this off-setting is to the left of the ordinary or normal printing point at which the type bars 7 strike, and which is indicated by the dotted line d in Fig. 3. 0f course, if the entire type system travels relatively to the platen, as in a flat platen machine, the ofi'- setting of the type would be to the right of the ordinary printing point; the object being in each instance to write the accent mark above or below a previously written letter, as indicated in Fig 9, immediately the carriage has completed its letter space movement after writing such letter.

This off-setting of the type block on the type bar 2() has heretofore presented the ditliculty or objection that in the ordinary construction there would not be sufficient room for it in the basket when said bar returns to its position of rest, represented in Fig; 5,

-and it would collide with the adjacent type bar 7. lt is to avoid this difficulty that I cut the slot 18 of the accent type bar 20 in a non-radial plane b and bend the type bar. After the bar is mounted in its slot the shank or body portion thereof is bent laterally at 20X from the plane of the slot (indicated by the dotted line Zn) to the full line position of the bar represented in Fig. 8, so as to brlng the type thereon in proper position with reference to the printingr line and enable the bar to properly enter the type guide; the body portion of the bar converging to the same point as the bars mounted in the radial slots. When the type bar 20 returns to rest in the basket the body portion thereof flares away from the adjacent bar 7, as indicated in Fig. 5 thus providing ample room in the basket for the type bar 20 and its type block.

The left-hand accent bar 19 has a double i bend 24 and 25 to olf-set the type block to bar 20, carries it away from the block of the adjacent bar. Therefore, there is sutlicient room in the basket for the type bar 19 and itis unnecessary, in this instance, to make its bearing slot non-radial and bend the body portion of the bar laterally with reference to the plane of its slot, as in the case of the bar 20.

The means for actuating the type bars may be of any suitable construction. In the present instance, they are the means employed in the improved No. 10 Remington machine and consist of spring returned key levers 26 fulcrumed on a bar 27 and each provided with a finger key 28; the finger keys of the left and right-hand accent bars being represented respectively in Figs. 7 and 8. Each` key lever is pivoted `at 29 to a sub-lever 30 that is fulcrumed at 31 and carries a laterally projecting headed pin 32 at its upper end. Fach pin 32 enters a slot 33 of the companion type bar and by a depression of the companion key the type bar is moved to printing position. l

As hereinbefore indicated, each of the ordinary type bars 7 during a printing operation actuates the universal bar 5 and the escapement mechanism controlled thereby and effects a letter feed of the carriage` However. in order that each of the accent bars 19 and 20 may operate to print without effecting a feed of the carriage, I cut away the contact 6 on each bar. as indicated by the notch 34 in the heel thereof. Therefore, each of the accent bars 19 and 20 is inoperative on the universal bar It is necessary, however, when using the ribbon vibrator 35 to actuate it at each operation of an accent key. as well as at an actuation of each of the ordinary printing keys. T therefore provide an independent universal bar 36 for actuating the ribbon vibrator. This universal bar extends beneath the key levers and is acted on by a projecting finger 37 carried by each accent key lever, as well as by each of the key levers of the ordinary actions. The universal bar 36 is carried by arms 38 connected with a rock shaft 39. This shaft is provided with an upright arm 40 slotted at its upper end, as at 41, to lreceive a grooved roller 42 carried by a rod 43 supported between depending arms -44 of an actuating frame. This frame is pivoted at 45 to a fixed part 46 of the machine, and is operatively connected by the usual means (not shown) to the lribbon vibrator, substantially as represented in my Patent No. 1,203,795,

dated November 7, 1916. It will be under-v stood, therefore, that at each operation of an accent key as well as Vat each operation of a key lever of an ordinary type action, .the vibrator will be elevated to bringV the ribbon into the path of the type on the actuated type bar.. A

It will be seen that, if desired, the accent type bar 19 may be replaced by an ordinary bar 7. If, on the other hand, it be desired to provide more than four accent types, one or more additional non-radial slots may be provided atthe right-hand side of the segment in which to. mount accent type bars somewhat like the type bar 20. Thus, from anv inspectionof Fig. 6 it will be seen that the slot 47, second from the righthand end of the series, is cut in the nonradial plane indicated by the dotted line e, and that the upper end of thisline is about U of an inch below the point of convergence of the planes of the radially disposed slots, indicated by the upperv ends of the dotted lines a, a and f. In Fig-6, the extreme right-hand end slot 48 1s, however,

cut on a plane represented by the dotted line g, the upper. end of which is about zU of an inch below the point of l.convergence of the planes of the radial slots. By slotting the segment in this manner and bending the two bars received in the two righthand non-radial slots 47 and 48 laterally of said -planes as previously described, room is provided in the basket for off-setting the type blocks on two right-hand accent bars such as 20. i

From the foregoing description it will be understood that I have provided simple and eiicient dead key mechanism while providing ample room in the basketof a front strike or visible machine for the desired number of type bars having off-set accent type blocks'.

In a companion application led `J une 3, 1921, Sr. No. 474,700, I have included claims which dominate certain features of the present invention; claims of the present case being restricted to, features not disclosed in said companion application.
